Answer 1

Devendra Kanade ,

this is what wikipedia says:

*ASCII, an acronym for American Standard Code for Information Interchange, is a character encoding standard for electronic communication. ASCII codes represent text in computers, telecommunications equipment, and other devices. ASCII has just 128 code points, of which only 95 are printable characters, which severely limit its scope.*

this coding is from the early days of computer technology, and has several issues when characters from various languages are used.
so this system was enhanced and is named *Unicode*, where much more different characters for nearly all languages are defined by a number.
